When and where clapping originated is now impossible to verify. In China, the earliest written record of clapping is found in the article Han Fei, a representative figure of pre-Qin legalist school, Han Fei's "Han Fei Zi Gong Ming". The article said: "The man is in trouble, so he said: single-handedly, although silent." The implication is that clap your hands will make a sound. Of course, its original intention is far from what people often say later, "one sound and two rings". This shows that there was applause around 230 BC.
Applause means applause in English, which comes from Latin plateader e. Plautus, an ancient Roman playwright in 200 BC, always wrote Plaudite at the end of his plays, telling the audience not to forget to clap their hands or hit objects to express their gratitude. Drama is the earliest source of applause in the west. Westerners like to watch plays and listen to songs, and applause has gradually become a etiquette in the theater. However, music is a complicated thing, and many people don't understand it, let alone know when and where to clap. At this time, professional "clappers" came into being. They sat in the front row, applauded first, and induced the audience in the back row to applaud. In Italy in the middle of the19th century, a professional clapper earned 10 lira per lap. No wonder there is a saying "employee" in English.
